Abstract (en)

To stably control clutch engagement torque of a multidisk friction plate clutch (1045) provided between two rotary members (1029, 1033), without being directly subjected to the influence of friction plate wear or of fluctuations in friction coefficient between two clutch plates, the coupling apparatus comprises a pilot clutch (1061), a main clutch (1045) and dual cam ring members (1053) disposed between the two clutches. When the pilot clutch (1061) is engaged by an actuator (1063) in a first direction, since a first slidable cam ring (1047) rotation is limited by the pilot clutch relative to a second fixed cam ring (1049), the first slidable cam ring (1047) is shifted in a second opposite direction by a cam thrust force to engage the main clutch. The coupling apparatus is suitably incorporated in a differential gear assembly mounted on automotive vehicles in order to controllably and stably limit the differential motion between two shafts.
